Description
The
160mm to 110mm drainage branch is an unequal underground drainage fitting designed to connect a 110mm branch pipe into a larger 160mm main drainage run. This
160mm 110mm unequal T branch combines an
87.5 degree drainage branch layout with a
double socket drainage branch connection, creating a practical
160mm to 110mm pipe junction for compatible foul-water and surface-water drainage systems. Designed for below-ground gravity drainage, the fitting allows a smaller 110mm pipe to join a larger 160mm system while maintaining a secure ring-seal connection.
160mm to 110mm Drainage Branch
The
160mm to 110mm drainage branch is ideal where a smaller property drain, gully line or other compatible 110mm pipe needs to enter a larger 160mm underground drainage run. The unequal configuration means the main pipe remains 160mm while the side branch reduces to 110mm.
Choosing a 160mm to 110mm Drainage Branch
Use the
160mm to 110mm drainage branch where the main underground drainage line is 160mm and the incoming connection is 110mm. Check that the adjoining pipes and fittings are dimensionally compatible before installation, particularly when components from different underground drainage systems are being combined.
160mm 110mm Unequal T Branch
The
160mm 110mm unequal T branch differs from an equal branch because the side connection is smaller than the main drainage run. This configuration is useful on larger domestic, commercial and groundwork systems where individual 110mm drainage lines feed into a 160mm main.
160mm to 110mm Drainage Branch Installation
Before installing the
160mm to 110mm drainage branch, make sure the sockets, seals and connecting pipe ends are clean and free from grit or damage. Use suitable underground drainage lubricant where required and push prepared pipe or spigot ends squarely into the ring-seal sockets without displacing the seals.
87.5 Degree Drainage Branch
The
87.5 degree drainage branch creates a near-right-angle connection between the smaller branch line and the 160mm main drainage run. An
87.5 degree drainage branch is commonly used where the incoming pipe needs to approach the main drain at approximately 90 degrees.
Using an 87.5 Degree Drainage Branch
When positioning an
87.5 degree drainage branch, consider the direction of flow, pipe fall and future maintenance access. Near-right-angle junctions should form part of a properly designed drainage system with suitable inspection or rodding access where required.
160mm to 110mm Drainage Branch with Double Socket Connection
The fitting uses a
double socket drainage branch arrangement for convenient ring-seal jointing within compatible underground drainage pipework. A
double socket drainage branch helps simplify installation by providing socketed connections at the required points rather than relying on additional separate couplers.
Double Socket Drainage Branch Installation
Before assembly, check that each socket seal is correctly seated. Keep the seals, sockets and pipe ends clean and use suitable drainage lubricant during installation. Avoid forcing the connection, as excessive pressure can displace or damage a ring seal.
160mm to 110mm Pipe Junction
The fitting creates a useful
160mm to 110mm pipe junction where a smaller 110mm drainage line needs to enter a larger underground system. A
160mm to 110mm pipe junction is commonly required on larger drainage layouts where individual property or surface-water connections feed into a main 160mm run.
Using a 160mm to 110mm Pipe Junction
When installing a
160mm to 110mm pipe junction, make sure the adjoining pipework is correctly aligned, bedded and supported so unnecessary movement or loading is not transferred into the branch fitting.
160mm to 110mm Drainage Branch Applications
The
160mm to 110mm drainage branch is suitable for compatible applications including:
- Connecting 110mm drainage into a 160mm main run
- Foul-water underground drainage
- Surface-water drainage
- Rainwater drainage systems
- Property drainage connections
- Domestic groundworks
- Commercial drainage installations
- Drainage repairs and alterations
PVC-U Underground Drainage
This type of fitting is designed for compatible PVC-U non-pressure underground drainage systems. PVC-U provides a lightweight, corrosion-resistant material widely used for underground foul-water and surface-water drainage.
Unequal Branch vs Equal Branch
An unequal branch connects pipes of different nominal sizes. On this fitting, the main drainage run is 160mm while the side branch connection is 110mm. If both the main pipe and side branch are 160mm, a 160mm equal branch should be selected instead.
87.5° T Branch vs 45° Y Branch
An
87.5 degree drainage branch creates a near-right-angle junction, while a 45° Y branch introduces the connecting pipe at a shallower angle. The correct branch depends on the drainage layout, direction of flow, available space and overall system design.
